Filtering Calculation Help

[CarbonSteel]

If you have two filters connected such that Filter 1's output is Filter 2's input (meaning the oil is filtered by Filter 1 and then filtered by Filter 2 before going back to the engine), does anyone know what the calculation would be to understand the filtration efficiency?

Thanks in advance for the help!

Dual remote filter setups are plumbed in parallel, not in series. If two identical oil filters were plumbed in series, you really aren't going to get any better filtration, all you'll do is be using the first filter from loading up the second filter. The first filter will essentially be doing all the work
